Tom Elrod commented on JBREM-51:
---------------------------------
One of the problems with using a data type for a custom Marshaller/UnMarshaller
is having to explicitly code the addition of these within the MarshalFactory on
both the client and the server. So another approach that is a little more
flexible is to specify the fully qualified class name for both the Marshaller
and UnMarshaller on the locator url. For example:
socket://myhost:5400/?datatype=invocation&marshaller=org.jboss.invocation.unified.marshall.InvocationMarshaller&unmarshaller=org.jboss.invocation.unified.marshall.InvocationUnMarshaller
This will prompt remoting to try to load and instantiate the Marshaller and
UnMarshaller classes. If both are found and loaded, they will automatically be
added to the MarshalFactory by data type, so will remain in memory. Now the
only requirement is that the custom Marshaller and UnMarshaller classes be
available on both the client and server's classpath.
Another requirement of the actual Marshaller and UnMarshaller classes is that
they have a void constructor. Otherwise loading of these will fail.
This configuration can also be applied using the service xml. If using
declaration of invoker using the InvokerLocator attribute, can simply add the
datatype, marshaller, and unmarshaller parameters to the defined InvokerLocator
attribute value. For example:
<attribute
name="InvokerLocator"><![CDATA[socket://${jboss.bind.address}:8084/?datatype=invocation&marshaller=org.jboss.invocation.unified.marshall.InvocationMarshaller&unmarshaller=org.jboss.invocation.unified.marshall.InvocationUnMarshaller]]></attribute>
If ware using config element to declare the invoker, will need to add an
attribute for each and include the isParam attribute set to true. For example:
<invoker transport="socket">
<attribute name="dataType" isParam="true">invocation</attribute>
<attribute name="marshaller"
isParam="true">org.jboss.invocation.unified.marshall.InvocationMarshaller</attribute>
<attribute name="unmarshaller"
isParam="true">org.jboss.invocation.unified.marshall.InvocationUnMarshaller</attribute>
</invoker>
